This invention relates to improvements in multi-sash windows of the type comprising a plurality of adjustable sashes mounted one above the other in a window frame.

The main purpose of this invention is to provide in a multi-sash. window of the character described, a simple, inexpensive, reliable and easily operable means for simul-v taneously opening and closing the. several sashes through manipulation of one of the sashes, which means also provides for independent opening and closing of the said operating sash while other'of the sashes are maintained in open position. By this arrangement the necessity of using sticks or poles or operating a plurality of control members to manipulate the sashes of a long or high window is eliminated and a great deal of time and efiort is saved in the adjustment and operation of the sashes.

The particular mechanism above referred to is specially constructed to eliminate friction and to insure reliability and ease of operation, said operating means being capable of being readily and easily set up in a Window frame and maintained in proper working condition while practically concealed from view.

The invention provides for the adjustment of the several sashes into and the maintaining of the sashes in any one of a plurality of positions between the fully closed and opened positions.

With the above mentioned and other ob-. jects in view,

the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings, and set forth in the claims hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the. spirit or sacrificing any of the advantages of the invention.

The invention as shown in the accompanying drawings comprises a window frame, the vertical members of which are each in the form of casings designated 1. In the frame a plurality of sashes, designated A, B and C, a

are mounted so as to be swung into and out of closed position, the operating mechanism for said windows being contained in said frame. The rear wall of each casing of the frame comprises angle iron bars 2 and 3, laid edge to edge and so that the portion 4 of the bar 2 may be anchored in the wall D, and the corresponding portion 5 of the bar 3 will project into the frame opening and serve as one of the walls of the casing. The other walls of the.casin are provided by flanged facing strips 6, T and.8, ofwhich the one 6 is fastened to the angle iron bar 3 and the ones 7 and 8 to the bar 2. angle iron strip 9 is fastened to the bar 2 and to it is anchored a channel strip 10 which is also fastened to the portion 5 of the bar 3. An angle iron bar 11 is fastened as at 11' to the bars 2 and 3 adjacent to the point where the latter abut one another. This angle iron strip is adapted to be embedded in the wall surrounding the window frame opening, as shown in F1g. 7

Sashes A, B and C are pivoted as at 12 intermediate of their upper and lower ends to arms 13 which are in turn pivoted as at 14 to members 15 on the window frame. The sash A is provided with arms 16 extending from its upper end into the casings of the window frame and pivoted as at 17 to slide bars 18. The slide bars 18 in addi tion to being vertically slidable in the window frame are adapted to be moved into and out of position to be locked with other slide bars which will be later described, in order that one of the sashes may be operated independent of other of the sashes. In the present embodiment of the invention these slide bars 18 are pivoted at their upper ends to shoes 19 which slide on tracks 20 fixed within the casings. When the lower sash is swung outward into open position, the members 16 push downward, the slide members 18. The slide members 18 are adapted to swing on their pivotal mountings and are urged towards the front sides of the casings by springs 21 so that the notches 22 at the lower ends of said members will be caused to receive projections 23 provided on slide bars 24 which are slidable vertically within the casings. The slide bars 18 are operated by levers 25 pivoted intermediate of their ends as at 26 to the channel strip 10 and extending below said strip within the casings of the window frame. The up er ends of these levers carrying clips 27 which loosely embrace the bars 18 and permit said bars to slide freely while providing for the desired connection between the levers and bars. The lower ends of the levers are pivoted as at 28 to operating members 29 that extend through openings 30in the easings of the window frame so that their outer ends will be accessible to the operator. On the pushing inwardly of these members 29, the levers will be rocked so as to move the bars 18 out of engagement with the projections 23, thus permitting free movement of the slide members 18 relative to the slide members 24. The members 29 are provided on their lower sides with notches 31 adapted to receive portions of the lower edges of the openings 30to lock the members 29, levers 25 'and bars 18 in position shown in Fig. 4, free from locking engagement with the slide bars 24. On release of the members 29, the springs will move the bars 18 into position such that the projections 23 on the bars 24 will engage in the notches 22 when said slide members are moved into certain positions.

The slide members 24 are made up of sections adjustably connected by means of providing slots 33 in certain sections and aving screws 34 extending through the slots and joining the sections together. This adjustment of theslide bars provides for setting the sashes so that they may be only partly opened or closed. Rotatably mounted on slide bars 24 are anti-friction wheels 35 and 36. Attached to the pins 37 on these rollers are mounted arms 38 and 39 which extend from the up er ends of the windows B and C. The w eels engage between and ride on the portions 5 of the bars 2 and angle iron pieces 9 attached to the bars 3. On movement of the slide bars 24 up and down, the windows B and C will be closed and opened due to the connection of the windows with the bars, through the arms 38 and 39.

As a means for holding the windows in position into which they are moved, whether fully or partly opened or closed, there is provided a friction clamping means generally designated 40, which means comprises plates 42 supported in the frame casings by screws 43 and engaging on channel pieces 44 fastened in the casings. A bowed leaf spring 45 is fastened centrally of its ends as at 46 to the plates 42 and at its ends bears upon friction plates 47, the ends of which plates are provided with flanges 48 to engage the ends of the spring. These plates in turn press on the slide bars 24 and the pressure is sufficient to maintain the bars in position into which they are moved. Adjacent their upper ends the slide bars 24 extend through guides 49 which are fastened within the casings of the window frame.

When the sashes are closed and the members 29 are in position shown in Fig. 3, the slide bars 18 for the lower sash are locked with the slide bars 24, the projections 23 on the last named bars engaging in the notches 22 on the bars 18. On now grasping the lower sash and pushing the same into open position, the several sashes will be opened si multaneously. The movement of the lower sash into open osition causes the arms 16 to press downwar ly on the bars 18, sliding said bars 18, also the bars 24, downward exertin an influence on the windows B and O through the arms 38 and 39 so as to open said windows. The friction clamping means 40 acts as described; to maintain the windows in any position into which they are moved by holding the bars 24'against unintentional movement. If it is now desired to operate the lowermost sash independent of the other sashes, or in other words to close the lower most sash while permitting the upper sashes to remain open, the operator pushes inwardly on the members 29 until the notches 31 receive the portions of the casing through which the members 29 slide, and said members 29 are locked in position shown in Fig. 4. On moving the members 29 inwardly, the levers 25 are rocked and swing the slide members 18 sothat the notches 22 will move clear of the projections 23 on the bars 24, said bars 18 being moved to one side and clear of the bars 24 as shown in Fig. 4. Thus, on now swinging the sash A into closed position, the bars 18 move relativeto the bars 24 and the lowermost sash may be operated as desired without changing the positions of the upper sashes.

When it is desired to operate the upper pushed upwardly through plurality of sashes the simply jections 23 on ing the slide bars 18 and 24 for simultaneous movement. On pulling inward or closing of the lower sash following this locking of the two sets of slide bars, the slide bars 24 are the arms 16 and all of the windows are simultaneously moved into closed position.

It will thus be seen that through the simple, easily operable means of this invention, a may be readily and easily controlled as desired, through manipulation of" one of the sashes. One of the important features of this invention is the provision of constructed, strong and durable operating means as illustrated and described int-his application, which operating means is practically concealed within the casings of the window frame and may be readily and easily operated to control the several sashes as desired without the annoyances and difliculties which usually attend the operation of 'multi-sash windows of the type to which this invention relates, The construction of this invention provides for ready and easy installation of multi-sash windows.
